I FASTENER-SETTING MACHINE. 7

To aZZ whom it may concern: I

Be it known that I, IRVING ErsrnIN, a citizen of the United States, and a resident of New York, county of New York, and State ofNew York, have invented certain new and useful Improvements in. Fastoner-Setting Machines, of which the fol lowing'is a specification.

This invention relates to machines which are adapted to employ a die and a plunger which cooperate'to fasten materials together or to distort an object acted upon by them, the machine embodied hereincomprising a plunger and die which permit a transverse, or, in the case of a vertically operating machine, a horizontal insertionand removal of objects operated on by the plunger.

The invention further resides in a holder on theplunger which permits of the insertion and removal of said objects from the plunger, theholder acting to hold the object except when undue pressure, as in removal, is applied to the object. 1

A further object of theinvention is to so mount the plungers and dies on a suitable and can *bemoved toward and from each other and also kept in proper alinement with each other, this being desired when affiXing more than one object at a time, for instance, in placing the buttons on the bottom of traveling bags, or in aflixing' the buckles to the bands at the knee seam in knickerbockers, and in numerous other situations, in some cases the adjustment being frequent and in other casesthe adjustment being very seldom utilized, it being, however, present for utilizationwhen necessary. I I

The invention is also designed to provide a feeding means to automatically project objects from a suitable source of supply, said objects being placedin the holder of the plunger, and in the case of the use of two plungers in the holders, with their corresponding dies, to provide for the adjustment of the feeding means with the dies and plungers, and'insure its operation in all adjustments.

The invention is illustrated in the accompanying drawings, in which i Figure 1 is a top View of an improved form of machine'illustrating my invention, and Fig.2 is a face view of the machine illustrated in Fig.1. Fig. 3 is a side view on an enlarged scale of the machine illustrated Specification of Letters Patent.

in Figs. 1 and 2, a portion thereof being shown in section. Fig. 4 is a detail showing one method of adjusting the plungers. F g. 5 s a section on line 5, 5, in Fig. 3, and Fig. 6 1s a section on line 6, 6, in Fig. 3; i

The illustration of my invention, and it will be understood that changes in detail and the arrangement of parts can be tration showing out my idea.

In the form shown in the drawing I illustrate a table 10 which can be suitably sup ported on legs or in any other manner, the table 10 in turn forming a support for the but one form of carrying shows one embodiment made in view of the illus- 1 remainderof the machine in so far as itapably support a post 12 which can be suitably operated, the'form shown consisting of a foot-lever l3 swinging at 14 and having a foot-plate 15 thereon and being normally held in position by a spring 16, theresistance of the spring being overcome by the pressure of the foot. The foot-lever is'con nected to the post 12 by a link 17. The post 12 is provided with a T-shaped frame -con-' sisting of the extension 18 and the arms 19, the arms l9 forming the head of the T and being arranged transversely of the machine, for purposes to be described hereinafter. I d

On each arm 19 is arranged a each plunger having a head which a screw 22 i a handle 23 and beiiigiheld against movement in thehead 21 by suitable securing means, the form shown consistingof a locking'screw 2a which fits into a groove 25 in the screw 22. A suitable locking-bolt 26 assists in holding the head, consequently its plunger, in the desired position, it being customary to unloosen the locking-bolt 26 21 through before the screw 22 is operated to shift the plunger 20,

passes, the screw having The bottom-plate 29 is provided viding for the lateral movement and adj ustment of the die.

a machine which is adapted for fastening buckles 36, the type of buckle shown being of the kind that is fastened to the knee straps of knickerbockers having the prongs 37 which arefiadapted to be bent into the material to which the buckle is attached, and thechute is made of the-proper crosssection .to conduct such buckles. If, however, rivets or any other suitable objects were to be conducted, the chute would be changedjto permit the passage of such objects through" the chute. I Suitable removable chutes, 38 canfbe used and can conduct objects from a suitable reservoir, or they loan be filled by hand and then removablyiipncea in the block 39, as will be evident. Lightsprings 4L0 atthe bottom end of thechute act to limit the downward movement] of the objects, suchv as the buckles, and a're so lightthat they vdo not interfere with the positive. feedingof the buckles when such a step is. due. ."Suitably'arrang'ed' on the bracketis an arm ll .on, which swings a lever-d2 pivoted M43 and having a slot 44: therein, the slotted endof ,theil'ever, which is arranged onv theextensionof the lever which passes through the signer; into the plunger 20, permitting the .operation of the lever from the plunger, At the inner end of the lever there; is a pivotal connection/i6 with a pawl 47, he Qpavvl having a nose 48, the nosebeing adapted to engage the objects in turn andf'ee'd them forward to a suitable holder? Thefltop surface of the lower end of the chute 35 is slotted as at 49 to permit the passage of the nose of the pawl, and to one side of?'thejend of the chute is a fenderp1ate 50 witli a step 51 which raises the pawlf'at the. end of its vbackward stroke, for purposes to be' described hereinafter. v

A] 'suitable.;.hol der forbbjects fed from the chute, consists oftwo members 52 and 53 which swing on a pinl5t which is arranged a' slot 55 of'the plunger 20. The members of the holder do not come together at the bottom, thus formingja space 56 for the dependinglportion of the object to be acted upon, ini 'this, 'casef the slot, being f wide enough to permit the vpassage of the prongs 3702f the buckle. Thepliin'gerQOQhaS an end 57 which extends downjinto the holder, and the pin 54:, on, which the vmembers swing, is movable on, thenplunger by reason of the slot 55.

- Springs 58 tendto norrnally swing the members. towardfeach otherv the required distance. A spring 59 abuts against the lu er i swee ia me -1y pm,

facilitated bya cut-away portion 63 in the plunger. 7 p v I A gagefi is arranged on a stem 65 and is fastened by a screw 66, this gage being used to limit the entrance ofivmaterial to which objects are to beattached The operation of the device is as follows: After a proper adjustment ofthewdies and the plungers so as to separate them by the I proper interval, in case theldevice is .to be used for simultaneously fastening objects at separated places, or for the purposeof acting in any other way on. material at separatedplaces,,the foot-lever 15is pressed, or

in the case ofv a power-driven;machine, the proper starting device is manipulated soas to forcethe plungers down, thedownward movement being regulated and limited by the stop-screw 67 and the step 68. The

holder going ,down with the plungercarries Withi t e bi ct. uch as thebmk 1 holder having two openasides fort the admission and removal 0f;the object to be afiixed, the, plunger and the holder-,going down, far enough-to permit the end of the plunger 57 to press the object acted upon, and in the case of buckle, pressing it hard enough to turn over the prongs 37, The plunger ,is permitted to move farther than the holder on account of the ,yieldingof the spring 59. During the, downwardgmovement of the plunger the leverv 42 is swung against the pressure of the spring 69 which normally forces thQ lQYQIT idownward the swinging of thelevenpulling back on the p 7-, he pawl as a P 111 W p res on the fender 50, and the pawl is usually light enough to pass over the, next object which-is heldin the end of thephuteagainst the springfingers 4C0 so as to get in the rear of the next succeeding object to feed it forward. In case, however, the objects. are very light, or if very few objects are follow? ingthe one in place and'the objects retreat w up thechute 35, the pawl, by reason ,of its pin 7Q engaging the step 151,, is lifted long enough to permit, the ,objects again; to ,slide forward in their places. When the plungers move upward, the article operatedon, or the apparel or the, like whichahas had objects, affixed to it, is pulled out from the machine, the object accompanying it by reason of the resiliency of the end 6210]": the spring ,59.

As the plunger audits holder move upward,

the holder beingcarried by reason of the} pin 54 being in the bottom of the slot 55, the lever 42 is swung to push the pawl 47 forward, and the nose 4L8 forces the object beyond the very light springs 40 and onto the bottom of the holder, and the next object is in place ready for a succeeding operation of the plungers. I

It will be evident from this description that a Wide adjustment laterally is permissible to adapt this press to a multiplicity of uses and to permit the affixing of objects simultaneously to apparel, leather goods, and other material, and insure their separation by proper distances, or making it possible to vary the distance between the objects afiixed or operated on.

I have described this machine primarily as a machine for aiiixing buckles and rivets or the like, but it will be evident that it is applicable to uses other than these, and I wish to be understood as not limiting my self to the particular uses which are embodied iin this specification, since slight changes might be made in the details of the construction to make it applicable to many different uses;

Having thus described my invention, what I claim is 1. A fastener setting machine consisting of a reciprocating post having a substantially T-shaped frame thereon, plungers arranged on the cross-piece of the frame, means on the cross-piece for adjusting the Copies of this patent may be obtained for five cents each, by addressing the plungers along the cross-piece, a table, brackets 'mounted on the table, means for adjusting the brackets on the table, a die on each bracket, a chute supported on each bracket to conduct objects to a position to be operated on by the plunger and die aforesaid, feeding means mounted on each bracket and adjustable therewith, and an operative connection between the feeding means and the plunger.

2. In a fastener setting machine, a plunger, a holder suspended on the plunger and slidable thereon, the holder being slotted at the bottom, yielding means for holding the holder in its normal position, the holder being open at its ends to permit the passage of objects through the slot, a die toward which the plunger is arranged to be moved and means for projecting objects into the holder through one of the open ends, said yielding means aforesaid consisting of a spring bearing on the plunger and bearing on the holder, said spring having a projecting end arranged to form a yielding stop for objects in the holder.

In testimony that I claim the foregoing, I have hereunto set my hand, this 2nd day of July, 1913.
